Both the "Yes we are" and the "No we are not" opinions claiming that it is written in the Bible/TaNaKH.
They that believe we aren't allowed to pronounce God’s Name, claiming that it is written in the Bible that only the high priest was allowed to pronounce God's Name one time a year, on the Day of Atonement. They say that only then he was allowed to pronounce the Name of the God of Abraham, Isaac and Jacob in the Holy of Holies.
They that believe that we are allowed to pronounce God's Name, say that it isn't just written in the Bible that we are allowed, but that it is commanded to pronounce the Name of our God.
This gave me the reason to dig in the Bible and take a good look at what is and isn't written about the Name of our God.
This article isn't meant to add to the discussion what the rightful pronunciation of the Name of our God is ... if we are allowed to pronounce the Holy Name of our God, that is. I believe that my pronunciation, dialect & (birth)language is/can be different then yours, and certainly different then during Moses' days and David's days.
